5.磁盘分区(启动Linux)

[root@centos7 ~]# fdisk -l(查看硬盘信息)

[root@centos7 ~]# fdisk /dev/sdb

Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

Device does not contain a recognized partition table

[root@centos7 ~]# ll /dev/sdb*

brw-rw---- 1 root disk 8, 16 Aug 3 22:44 /dev/sdb

brw-rw---- 1 root disk 8, 17 Aug 3 22:44 /dev/sdb1

6.创建文件系统(格式化)

[root@centos7 ~]# mkfs.xfs /dev/sdb1

meta-data=/dev/sdb1 isize=512 agcount=4, agsize=12992 blks

= sectsz=512 attr=2, projid32bit=1

= crc=1 finobt=0, sparse=0

data = bsize=4096 blocks=51968, imaxpct=25

= sunit=0 swidth=0 blks

naming =version 2 bsize=4096 ascii-ci=0 ftype=1

log =internal log bsize=4096 blocks=855, version=2

= sectsz=512 sunit=0 blks, lazy-count=1

realtime =none extsz=4096 blocks=0, rtextents=0

7.挂载硬盘

[root@centos7 ~]# mkdir -p /data(创建磁盘入口)

[root@centos7 ~]# mount /dev/sdb1 /data

8.检查

[root@centos7 ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda3 8.8G 1.8G 7.0G 21% /

devtmpfs 476M 0 476M 0% /dev

tmpfs 487M 0 487M 0% /dev/shm

tmpfs 487M 7.7M 479M 2% /run

tmpfs 487M 0 487M 0% /sys/fs/cgroup

tmpfs 98M 0 98M 0% /run/user/0

/dev/sdb1 200M 11M 190M 6% /data

9.永久挂载

1.mount命令写入到/etc/rc.local(开机自启动)

2.安装规则写入到/etc/fstab

[root@centos7 ~]# blkid(查看设备对应UID)

/dev/sda1: UUID="de6cdbf0-7d5a-475a-bb51-cde7e0627e06" TYPE="xfs"

检查是否成功挂载

[root@centos7 ~]# umount /data

[root@centos7 ~]# df -h

10.云服务器增加swap(默认是没有的)

查看swap

[root@Centos64 ~]# free -h

total used free shared buff/cache available

Mem: 972M 140M 643M 7.7M 189M 651M

Swap: 799M 0B 799M

创建指定大小(500M)的文件

[root@Centos64 ~]# dd if=/dev/zero of=/tmp/500m bs=1M count=500

500+0 records in

500+0 records out

524288000 bytes (524 MB) copied, 1.77195 s, 296 MB/s

if:表示input file,输入文件

of：表示output file,输出文件

bs:表示block size,每次复制多大的文件(块大小)

count:表示次数

[root@Centos64 ~]# cd /tmp

[root@Centos64 tmp]# ls

500m

ks-script-sqlIbG

systemd-private-42cda662aebf4ce4908bed9856d3ba64-chronyd.service-UJTw7B

vmware-root_6221-1690178113

yum.log

[root@Centos64 tmp]# file 500m

500m: data(数据文件)

将500m改变成swap(格式化)

[root@Centos64 tmp]# mkswap /tmp/500m

Setting up swapspace version 1, size = 511996 KiB

no label, UUID=c28cdc5c-9618-4788-91c5-1e0d383fe048

[root@Centos64 tmp]# file /tmp/500m

/tmp/500m: Linux/i386 swap file (new style), version 1 (4K pages),

size 127999 pages, no label, UUID=c28cdc5c-9618-4788-91c5-1e0d383fe048

生效挂载

[root@Centos64 ~]# free -h

total used free shared buff/cache available

Mem: 972M 140M 643M 7.7M 189M 651M

Swap: 799M 0B 799M

[root@Centos64 tmp]# swapon /tmp/500m

swapon: /tmp/500m: insecure permissions 0644, 0600 suggested.

[root@Centos64 tmp]# free -h

total used free shared buff/cache available

Mem: 972M 140M 124M 7.7M 707M 643M

Swap: 1.3G 0B 1.3G

显示swap的组成

[root@Centos64 tmp]# swapon -s

Filename Type Size Used Priority

/dev/sda2 partition 819196 0 -2

/tmp/500m file 511996 0 -3

永久挂载

[root@Centos64 tmp]# vi /etc/fstab

#

# /etc/fstab

UUID=37253269-2f21-49ad-9621-4e928674487d swap swap defaults 0 0

/tmp/500m swap defaults 0 0

关闭swap后加入的分区：swapoff /tmp/500m

特殊文件系统tmpfs,把数据写入到这个文件系统相当于写入到了内存中，用户读取文件更快

[root@Centos64 tmp]# mount -t tmpfs -o size=500m tmpfs /mem

[root@Centos64 tmp]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda3 9.1G 2.0G 7.1G 22% /

devtmpfs 476M 0 476M 0% /dev

tmpfs 487M 0 487M 0% /dev/shm

tmpfs 487M 7.7M 479M 2% /run

tmpfs 487M 0 487M 0% /sys/fs/cgroup

/dev/sda1 197M 105M 93M 54% /boot

tmpfs 98M 0 98M 0% /run/user/0

tmpfs 500M 0 500M 0% /mem

-t：指定类型

-o：指定大小

dd还可以测速

[root@Centos64 tmp]# dd if=/dev/zero of=/mem/600m bs=1M count=500

500+0 records in

500+0 records out

524288000 bytes (524 MB) copied, 1.39772 s, 375 MB/s(速度)

[root@Centos64 tmp]# dd if=/dev/zero of=/mem/600m bs=1M count=600

dd: error writing ‘/mem/600m’: No space left on device

501+0 records in

500+0 records out

524288000 bytes (524 MB) copied, 0.250703 s, 2.1 GB/s(速度)
